RFC 1447 Party MIB for SNMPv2 April 1993
1. Introduction
A network management system contains: several (potentially
many) nodes, each with a processing entity, termed an agent,
which has access to management instrumentation; at least one
management station; and, a management protocol, used to convey
management information between the agents and management
stations. Operations of the protocol are carried out under an
administrative framework which defines both authentication and
authorization policies.
Network management stations execute management applications
which monitor and control network elements. Network elements
are devices such as hosts, routers, terminal servers, etc.,
which are monitored and controlled through access to their
management information.
Management information is viewed as a collection of managed
objects, residing in a virtual information store, termed the
Management Information Base (MIB). Collections of related
objects are defined in MIB modules. These modules are written
using a subset of OSI's Abstract Syntax Notation One (ASN.1)
[1], termed the Structure of Management Information (SMI) [2].
The Administrative Model for SNMPv2 document [3] defines the
properties associated with SNMPv2 parties, SNMPv2 contexts,
and access control policies. It is the purpose of this
document, the Party MIB for SNMPv2, to define managed objects
which correspond to these properties.
1.1. A Note on Terminology
For the purpose of exposition, the original Internet-standard
Network Management Framework, as described in RFCs 1155, 1157,
and 1212, is termed the SNMP version 1 framework (SNMPv1).
The current framework is termed the SNMP version 2 framework
(SNMPv2).

-- textual conventions
Party ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Denotes a SNMPv2 party identifier.
Note that agents may impose implementation
limitations on the length of OIDs used to identify
Parties. As such, management stations creating
new parties should be aware that using an
excessively long OID may result in the agent
refusing to perform the set operation and instead
returning the appropriate error response, e.g.,
noCreation."
SYNTAX OBJECT IDENTIFIER
TAddress ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Denotes a transport service address.
For snmpUDPDomain, a TAddress is 6 octets long,
the initial 4 octets containing the IP-address in
network-byte order and the last 2 containing the
UDP port in network-byte order. Consult [5] for
further information on snmpUDPDomain."

DESCRIPTION
"A party's authentication clock - a non-negative
integer which is incremented as specified/allowed
by the party's Authentication Protocol.
For noAuth, a party's authentication clock is
unused and its value is undefined.
For v2md5AuthProtocol, a party's authentication
clock is a relative clock with 1-second
granularity."

DESCRIPTION
"Denotes a SNMPv2 context identifier.
Note that agents may impose implementation
limitations on the length of OIDs used to identify

RFC 1447 Party MIB for SNMPv2 April 1993
-- Definition of Initial Party and Context Identifiers
-- When devices are installed, they need to be configured
-- with an initial set of SNMPv2 parties and contexts. The
-- configuration of SNMPv2 parties and contexts requires (among
-- other things) the assignment of several OBJECT IDENTIFIERs.
-- Any local network administration can obtain the delegated
-- authority necessary to assign its own OBJECT IDENTIFIERs.
-- However, to provide for those administrations who have not
-- obtained the necessary authority, this document allocates a
-- branch of the naming tree for use with the following
-- conventions.
initialPartyId OBJECT IDENTIFIER ::= { partyAdmin 3 }
initialContextId
OBJECT IDENTIFIER ::= { partyAdmin 4 }
-- Note these are identified as "initial" party and context
-- identifiers since these allow secure SNMPv2 communication
-- to proceed, thereby allowing further SNMPv2 parties to be
-- configured through use of the SNMPv2 itself.
-- The following definitions identify a party identifier, and
-- specify the initial values of various object instances
-- indexed by that identifier. In addition, the SNMPv2
-- context, access control policy, and MIB view information
-- assigned, by convention, are identified.
RFC 1447 Party MIB for SNMPv2 April 1993
-- Party Identifiers for use as initial SNMPv2 parties
-- at IP address a.b.c.d
-- Note that for all OBJECT IDENTIFIERs assigned under
-- initialPartyId, the four sub-identifiers immediately
-- following initialPartyId represent the four octets of
-- an IP address. Initial party identifiers for other address
-- families are assigned under a different OBJECT IDENTIFIER,
-- as defined elsewhere.
-- Devices which support SNMPv2 as entities acting in an
-- agent role, and accessed via the snmpUDPDomain transport
-- domain, are required to be configured with the appropriate
-- set of the following as implicit assignments as and when
-- they are configured with an IP address. The appropriate
-- set is all those applicable to the authentication and
-- privacy protocols supported by the device.

this variable may be altered by a management
operation (e.g., a SNMPv2 Set-Request), its value
can never be retrieved by a management operation:
when read, the value of this variable is the zero
length OCTET STRING.
The private authentication key is NOT directly
represented by the value of this variable, but
rather it is represented according to an encoding.
This encoding is the bitwise exclusive-OR of the
old key with the new key, i.e., of the old private
authentication key (prior to the alteration) with
the new private authentication key (after the
alteration). Thus, when processing a received
protocol Set operation, the new private
authentication key is obtained from the value of
this variable as the result of a bitwise
exclusive-OR of the variable's value and the old
private authentication key. In calculating the
exclusive-OR, if the old key is shorter than the
new key, zero-valued padding is appended to the
old key. If no value for the old key exists, a
zero-length OCTET STRING is used in the
calculation."

DESCRIPTION
"A publically-readable value for the party.
Depending on the party's authentication protocol,
this value may be needed to support the party's
authentication protocol. Alternatively, it may be
used by a manager during the procedure for
altering secret information about a party. (For
example, by altering the value of an instance of
this object in the same SNMPv2 Set-Request used to
update an instance of partyAuthPrivate, a
subsequent Get-Request can determine if the Set-
Request was successful in the event that no
response to the Set-Request is received, see [4].)
The length of the value is dependent on the

{ 0 0 } is returned.
This value must be written exactly once, when the
associated instance of partyStatus either does not
exist or has the value `notReady'. When written,
the value identifies a party, the cloning party,
whose status column has the value `active'. The
cloning party is used in two ways.
One, if instances of the following objects do not
exist for the party being created, then they are
created with values identical to those of the
corresponding objects for the cloning party:

A party is not qualified for activation until
instances of all columns of its partyEntry row
have an appropriate value. In particular:
A value must be written to the Party's
partyCloneFrom object.
If the Party's partyAuthProtocol object has the
value md5AuthProtocol, then the corresponding
instance of partyAuthPrivate must contain a
secret of the appropriate length. Further, at
least one management protocol set operation
updating the value of the party's
partyAuthPrivate object must be successfully
processed, before the partyAuthPrivate column is
considered appropriately configured.
If the Party's partyPrivProtocol object has the
value desPrivProtocol, then the corresponding
instance of partyPrivPrivate must contain a
secret of the appropriate length. Further, at
least one management protocol set operation
updating the value of the party's
partyPrivPrivate object must be successfully
processed, before the partyPrivPrivate column is
considered appropriately configured.

viewTable OBJECT-TYPE
SYNTAX SEQUENCE OF ViewEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Locally held information about the MIB views
known to this SNMPv2 entity.
Each SNMPv2 context which is locally accessible
has a single MIB view which is defined by two
collections of view subtrees: the included view
subtrees, and the excluded view subtrees. Every
such subtree, both included and excluded, is
defined in this table.
To determine if a particular object instance is in
a particular MIB view, compare the object
instance's OBJECT IDENTIFIER with each of the MIB
view's entries in this table. If none match, then
the object instance is not in the MIB view. If
one or more match, then the object instance is
included in, or excluded from, the MIB view
according to the value of viewType in the entry
whose value of viewSubtree has the most sub-
identifiers. If multiple entries match and have
the same number of sub-identifiers, then the
lexicographically greatest instance of viewType
determines the inclusion or exclusion.
An object instance's OBJECT IDENTIFIER X matches
an entry in this table when the number of sub-
identifiers in X is at least as many as in the
value of viewSubtree for the entry, and each sub-
identifier in the value of viewSubtree matches its
corresponding sub-identifier in X. Two sub-
identifiers match either if the corresponding bit
of viewMask is zero (the 'wild card' value), or if
they are equal.
Due to this 'wild card' capability, we introduce
RFC 1447 Party MIB for SNMPv2 April 1993
the term, a 'family' of view subtrees, to refer to
the set of subtrees defined by a particular
combination of values of viewSubtree and viewMask.
In the case where no 'wild card' is defined in
viewMask, the family of view subtrees reduces to a
single view subtree."

DESCRIPTION
"Information on a particular family of view

overall number of entries in the viewTable."

SYNTAX OCTET STRING (SIZE (0..16))
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The bit mask which, in combination with the
corresponding instance of viewSubtree, defines a
family of view subtrees.
Each bit of this bit mask corresponds to a sub-
identifier of viewSubtree, with the most
significant bit of the i-th octet of this octet
string value (extended if necessary, see below)
corresponding to the (8*i - 7)-th sub-identifier,
and the least significant bit of the i-th octet of
this octet string corresponding to the (8*i)-th
sub-identifier, where i is in the range 1 through
16.
Each bit of this bit mask specifies whether or not
the corresponding sub-identifiers must match when
determining if an OBJECT IDENTIFIER is in this
family of view subtrees; a '1' indicates that an
exact match must occur; a '0' indicates 'wild
card', i.e., any sub-identifier value matches.
RFC 1447 Party MIB for SNMPv2 April 1993
Thus, the OBJECT IDENTIFIER X of an object
instance is contained in a family of view subtrees
if the following criteria are met:
for each sub-identifier of the value of
viewSubtree, either:
the i-th bit of viewMask is 0, or
the i-th sub-identifier of X is equal to
the i-th sub-identifier of the value of
viewSubtree.
If the value of this bit mask is M bits long and
there are more than M sub-identifiers in the
corresponding instance of viewSubtree, then the
bit mask is extended with 1's to be the required
length.
Note that when the value of this object is the
zero-length string, this extension rule results in
a mask of all-1's being used (i.e., no 'wild
card'), and the family of view subtrees is the one
view subtree uniquely identified by the
corresponding instance of viewSubtree."
